CONSTRUCTION METHOD AND APPARATUS FOR INSULATED WALL OF CRYOGENIC STORAGE TANK

摘要

PURPOSE: An insulation wall construction method of a low temperature storage tank diminishing the loss of a material is provided to prevent the deterioration of the work environment due to the dust by forming foam of predetermined thickness. CONSTITUTION: A two-component type urethane primer is spread within a low-temperature storage tank(S30). A spacer is combined to the up and down perpendicular in the inner side of the exterior wall(S50). The spacer is separated in a circumference direction. A reinforcing plate is separated between the spacers from the inner side of the exterior wall in a predetermined distance(S60). In the space among the inner side of the exterior wall and reinforcement plate, the polyurethane crude liquid is inserted(S90).
